When we moved here a neighbor told us not to plant our veggie garden until after the field was sprayed behind us because the roundup would kill It all. We put up a 6 foot privacy
fence and I planted shrubs ad small
trees that would get tall yet stay narrow against the
fence and encircling the lot to help stop any wind drift. This helped slow weed seeds that blew in the wind also.
I had soil brought in to regraded the lot so no
water would collect from adjacent properties. I use raised beds also. I did make the mistake early on of using treated lumber for some beds so I bough aluminum roof flashing and covered the treated
wood.
I pestered the
city until I finally got the ditch along the road dug out so that water no longer stands from off the road.
I keep a nice cover of wood chips on paths and throughout the gardens. I get a lot of
mushrooms growing in it and I have read that they will detox soil.
The field behind us is now houses so I don't have those chemicals against my lot now but I will be watching this tread for other steps to take.
